Y = 100x + 200
charge for three days of rental; $500
explanation:
y = 100(3) + 200
y = 300 + 200
y = 500
Divide the speed in kmph by 1.6 to get miles per hour.
110 / 1.6 = 68.75 miles per hour
Multiply the speed by the time.
68.75 x 5 = 343.75 miles in 5 hours.
Answer:
x = 5
Step-by-step explanation:
x/2 = 15/6
6 * x = 15 * 2
6x = 30
x = 30 / 6
x = 5
-2x - 2y = 4
x + 5y = 10
It looks like the method it would be easiest to use to solve this system is substitution. To use substitution, let us isolate x in the second equation:
x + 5y = 10
x = -5y + 10
---
-2x - 2y = 4
-2(-5y + 10) - 2y = 4
10y - 20 - 2y = 4
8y - 20 = 4
8y = 24
y = 3
Now we can substitute back into the second equation to find x:
x + 5y = 10
x + 5(3) = 10
x + 15 = 10
x = -5
Finally, to check our work:
-2(-5) - 2(3) = 4 --> 10 - 6 = 4 <--True
-5 + 5(3) = 10 --> -5 + 15 = 10 <--True
Answer:
y = 3
x = -5
Answer:
see explanation
Step-by-step explanation:
Given
> - 16 ( multiply both sides by 4 )
x > - 64
To show the solution on a number line
Place an open circle ( indicating x ≠ - 64 ) at - 64
greater than - 64 is to the right of - 64 , hence the direction of the shaded line points to the right of - 64
